High Fidelity Dynamics


Hyfydy is a new physics engine for high-performance musculoskeletal or biomechanical simulation. It provides a 50-100x speed gain over OpenSim, while using the same muscle and contact models. For more information, check out the features page or send us a message.


Hyfydy is currently available for use in academic research. It can be downloaded as a plug-in for SCONE, which is open source software for predictive simulation of human and animal motion. If you are already familiar with SCONE, you can request a free trial.

Why Hyfydy?


Simulate musculoskeletal models 50-100x faster than OpenSim.


High, user-controllable simulation accuracy.


Efficient error control ensures robust simulation.
